ARCServe 6.61 in a Clustered Environment

I am currently running NT 4.0 SP6, Exchange 5.5 SP3 in a clustered environment on COMPAQ Proliant servers.

In attempting to install ARCServe 6.61 I have lost the exchange administrative shares plus the ablity to map to other network shares.

The indication is that “irpstacksize” is to small. However, increasing the “irpstacksize” does not correct the problem.

Any throughts?

Is ARCServe 6.61 really cluster aware?
